And here is another study. Strictly for fathers.

Abstract

Whether a newborn child looks like the putative father is used to construct estimates of the impact of father visitation on the health of one-year old children. These estimates are not biased by the effect of a baby’s initial health on father visits, unobserved maternal ability, or measurement errors, thereby eliminating endogeneity biases that plague existing studies. Analysis of data from the first two waves of the Fragile Family and Child Wellbeing study indicates an extra day (per month) of father visitation raises the chance of reported excellent child health by 3 percentage points. Moreover, the impact of father visitation is more important when maternal earnings are low.

Our findings support father-child resemblance as a paternity cue used by men to determine whether to make time-investments. Moreover, we find, even after several robustness and validity checks, that father visitation, in response to baby looks, causes an increase in child health. Specifically, our basic result is that an extra visitation day reduces the incidence of reportedly low health by about 2 percentage points and increase the chance of reportedly excellent health by about 3 percentage points. Furthermore, the health contribution of the visiting father increases with lower maternal earnings. This study therefore supports father visitation policies for delivering improvements in early childhood health, especially for single working mothers with relatively low earnings. Indeed, the National Quality Improvement Center for Non-Resident Fathers was created in 2006 by the US child welfare system to promote non-resident father engagement with children in the welfare system.
